If the area of the circle equals 500 cm², find its circumference.

Answer: i think that's right if not than t don't have a solution

Step-by-step explanation:4(m−9)=2(2m+1)−40

(4)(m)+(4)(−9)=(2)(2m)+(2)(1)+−40(Distribute)

4m+−36=4m+2+−40

4m−36=(4m)+(2+−40)(Combine Like Terms)

4m−36=4m+−38

4m−36=4m−38

Step 2: Subtract 4m from both sides.

4m−36−4m=4m−38−4m

−36=−38

Step 3: Add 36 to both sides.

−36+36=−38+36

0=−2

Answer:

1/2

Step-by-step explanation:

3/4+3/8=9/8

9/8-5/8=1/2

Answer:

1/2 is left in Luna's glass

Step-by-step explanation:

3/4 is the same as 6/8

So 6/8 + 3/8 = 9/8

9/8 - 5/8 = 4/8.

4/8 can be simplified to 2/4, which can be simplified to 1/2

Answer:

$75.14

Step-by-step explanation:

The new value of one share of LMNOP stock after 11.6% increment is $75.14

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, we are given that:

Now, the 11.6% of initial price is:

[tex]\dfrac{85}{100} \times 11.6 = \$9.86[/tex]

Thus, the final price of the stock in December =  $85 - $9.86 = $75.14

x = 49

Step-by-step explanation:

AD is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides , that is

[tex]\frac{28}{x}[/tex] = [tex]\frac{8}{14}[/tex] ( cross- multiply )

8x = 392 ( divide both sides by 8 )

Step-by-step explanation:

A ton is 2000 lbs   ->    w = 2000

Weight in an elevator must be less than 2000   ->  w<2000

The pool must hold atleast 2000 lbs w >= 2000   (>=  is greater than equal to)

The scale......   ->   w<= 2000

My car weighs more than 2000    ->  w > 2000

Answer:

$23,360

Step-by-step explanation:

Calculation to determine how much carol originally invested in the account

First step is to divide £23517.60 by 1.025

= (23,517.60)/(1+.025)

= (23,517.60)/1.025

=$22,944

Second step is to add back the $1,000 withdrew

=$22,944+$1,000

=$23,944

Now let calculate how much carol originally invested in the account

$23,944=1.025P

Divide both side by 1.025

P=$23,944/1.025

P=$23,360

Therefore the amount that carol originally invested in the account is $23,360

Answer:

[tex]15.32[/tex]

Step-by-step explanation:

Eleven and seven-hundredths [tex]=11+\frac{7}{100}[/tex]

(Here, [tex]\frac{1}{100}[/tex] denotes the hundredth)

Four and twenty-five hundredth [tex]=4+\frac{25}{100}[/tex]

Therefore,

Sum of Eleven and seven-hundredths added to four and twenty-five hundredth = [tex]11+\frac{7}{100}+4+\frac{25}{100}[/tex]

[tex]=15+\frac{32}{100}[/tex]

[tex]=15+0.32[/tex]

Answer:

18.73 feets

Step-by-step explanation:

Given that:

Horizontal distance between ground and foot of flagpole = 7 feets

Lenght of wire = 20 feets

The height of the flagpole, h can be obtained using Pythagoras :

Adjacent = sqrt( hypotenus² - opposite²)

Height of flagpole = sqrt((length of wire)² - (horizontal distance between ground and flagpole)²)

Let height of flagpole = h

h = sqrt(20² - 7²)

h = sqrt(400 - 49)

h = sqrt(351)

h = 18.73 feets
